Additionally, Mary and the couple's four children, Prince Christian, eight, Princess Isabella, six, and three-year-old twins Prince Vincent and Princess Josephine, are set to attend the family dress rehearsal for the second semi-final, which is to be held on May 4.

At the dress rehearsal, the Australian-born royal will be able to catch a performance from Jessica Mauboy, a 25-year-old Australian singer who is one of the guest performers at the semi-finals.

Copenhagen was selected to host this year's contest after Denmark's Emmelie de Forest triumphed in 2013, landing 281 points for her song 'Only Teardrops'.

While a number of countries will fight it out for their place in the final, the UK, France, Spain, Italy and Germany automatically qualify, as does the host country.

This year, Denmark - who are hosting for the third time in the competition's 59-year history - will be represented by Basim, who will perform 'Cliche Love Song'.
